CARL ELBROWN, OF COLUMBUS, OHIO.

OIL-BURNER.

To all whom it may c0nccm:

Be itknown that I CARL E. BROWN, a citizen of the United States, residing at C0- lumbus, in the county of Franklin and State of Ohio, have invented a new and useful OiLBurner, of which the following is a specification.

The device forming the subject matter of this application is an oil burner of that general type which is shown in my prior Patent No. 1,184,616, granted on the 23rd day of May, 1916.

In the oil burner above mentioned, two improvements are proposed, in combination. First, the upper arm of the U-shaped pipe is provided with a return bend, constituting an inlet pipe, the construction being such that the fluid fuel, having been turned into gas, is superheated, before it is delivered to the lower arm of the U-shaped pipe. As a second and further improvement, it is proposed to alter the construction of the flame spreaders and to enhance their efficiency.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the c0mbination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in side elevation, a device constructed in accordance with the present invention, parts being broken away;

Fig. 2 is a section on the line 22 of Fig. 1; and

Fig. 3 is a section on the line 3-3 of Fig. 1.

The device forming the subject matter of this application resembles in many particulars the burner shown in my prior patent above alluded to. The description in this specification may, accordingly, be shortened. Proper notice will be given when the description departs from that which is old and relates to that which is new.

The structure forming the subject matter of this application preferably is fashioned from metal throughout, saving as hereinafter specifically modified, and comprises a boXlike casing 1 including a lid 2 which may be removable. At its ends, the lid 2 is provided with upstanding pyramidal Specification of Letters Patent.

combustion chambers 3, open at their lower ends so as to communicate with the interior of the casing 1, the smaller upper ends of the combustion chambers 3 terminating in outlets 4. The construction, therefore, is

such that air may be drawn upwardly upstanding flanges 7 defining a tray which may be filled with a layer of ashes, with asbestos, or with any other suitable absorbent material, denoted by' the numeral 8.

The invention contemplates the use of a U-shaped or arched pipe 9, comprising an upper arm 10" and a lower arm 11. The upper arm 10 of the pipe 9 lies above the outlets 4: of the combustion chambers 3, the lower arm 11 passing through the openings 5 in the combustion chambers, the arms of the pipe 9 being united by a bend 12, and the extremity of the lower arm 11 being closed by a cap 1 1 or in any other suitable manner. The lower arm 11 of the pipe 9 is provided with combustion orifices 16 lying within the contour of the chambers 3 and preferably disposed coaXially with respect to the openings or outlets 4. The pipe 9 is supported by means of a bracket 15 construction, the bracket being secured to the lid 2 and supporting the upper arm 10 of the pipe 9.

In order that fuel may be discharged into the tray or lid 2 and onto the absorbent layer 8, without shifting the pipe 9 endwise, a pair of discharge members 18 are located partly within the combustion chambers 3 and lie beneath the orifices 16. The discharge members 18 slant downwardly toward each other and pass through the slots 6 in the walls of the chambers 3, the inner or adjacent ends of the discharge members being secured to the lid or tray 2 within the contour of the tray. The outer ends of the discharge members 18 may bear against the under edge of the lower arm 11 of the pipe. It will be understood that when it is desired to deposit a priming charge in the tray, 3. quantity of oil or fuel is permitted to run out of the orifices 16, the oil flowing out of the discharge members 18, and passing therefrom to the absorbent material 8 in the tray or lid 2.

The foregoing features are shown in my prior patent above mentioned, and the novel elements of the structure will now be set forth.

Attached to one end of the upper arm 10 of the arched pipe 9, by means of a U 17 is an inlet pipe '50 disposed in the same horizontal plane with the pipe 10 and arranged parallel thereto. By means of a coupling 19 and elbows 20 and 21, or in any suitable manner, the pipe 50 is connected with a fuel supply pipe 22.

The invention comprises a pair of flame spreaders 23 located above the outlets 4; of the combustion chambers 3. Each flame spreader 23 includes downwardly diverging sides 24, united by a single upright wall 25. The sides 2 1 and the walls 25 of the flame spreaders 23 rest on the pipes 10 and 50. The upright walls 25 are disposed at the outer ends of the flame Spreaders, the inner ends of the flame spreaders being open. Consequently, the flame proceeding from the orifices 16 through the outlets 4 of the com bustion chambers 3 will not only be directed toward the median longitudinal plane of the device, but will also be directed inwardly toward the median transverse plane of the structure, that is, toward the bracket 15. The bracket 15 serves to support the pipe 50, as well as the arm 10.

In practical operation, fuel enters the pipe by way of the member 22 and is highly heated and converted into a gas. This gas then traverses the arm 10 and is superheated, the superheated gas passing into the lower arm 11 by way of the bend 12, and burning at the orifices 16.

Owing to the fact that the device herein disclosed includes the pipes 10 and 50, clearly shown in Fig. 2, the gas will be superheated before it is delivered into the lower arm or pipe 11. As a consequence, the efficiency of the structure is enhanced greatly, and it has been found by actual test that the oil consumption in a device of the type herein disclosed is reduced greatly, as compared with the oil consumption in a burner of the kind shown in my prior patent hereinbefore alluded to.

Having thus described the invention, what is claimed is In a device of the class described, a combustion chamber having an outlet at its top; a U-shaped pipe comprising upper and lower arms, the lower arm passing through the combustion chamber and having a burner orifice located within the contour of the chamber, the upper arm being provided with a return bend disposed in approximate parallelism with the upper arm and disposed approximately in a common horizontal plane with the upper arm, the upper arm and the return bend lying above the outlet for the combustion chamber; means for supplying fuel to the return bend; and a flame spreader including downwardly diverging walls engaged respectively with the return bend and with the upper arm, the diverging walls of the flame spreader being connected at one end by a transverse wall.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
